Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.
I see lots of correctables and un-correctables that need to be zero:
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

https://highspeed.tips/docsis-events/Thanks so much FURRYe38 , I will try these out as soon as I can get Comcast out here.
I'm using the CAX80 as my modem and my router, btw, in case that changes anything.
So these correctables and uncorrectables are all bad to see right? Should I expect to see none of those in the diagnostic report, in a properly functioning modem/coax cable setup?
